Description

Technical Field

[0001] The utility model relates to the field of air ducts, in particular to a heat-insulating air duct. Background Art

[0002] Insulated air duct is made by pasting insulation cotton on the inner wall of the duct instead of pasting insulation cotton on the outer wall of the duct during the production process of traditional galvanized thin steel plate flange air duct. The diameter of the air duct is the inner diameter after pasting the insulation cotton, and it can be fully automatically produced through CNC assembly line.
